I knew they wouldn’t last, because Supernatural isn’t about romantic relationships. Not long term. But Lisa was one of the best things to happen to Dean. She accepted him for who he is. She took him in at his lowest. She kept him grounded and moving forward at a time when he could have spiraled out of control. She gave him a year of something he’s always wanted… a normal life. She told him what that year meant to her.

Lisa was a strong, loving woman. Exactly what Dean needed. I will always love Lisa for taking care of Dean for that year of his life.

The thing with that Joker and Harley world is, you just want to see
more of it. And we all feel that way. There’s so many stories and it’s
such an amazing relationship and dynamic, as individuals and together,
it’s just an endless thing to discover, really. - Kate Hawley (costume designer)
